To 'all whom' fit may concern:

Be it known that I, Mn'rrmw A. Goonsrnno, a citizen of the UnitedStates, residing at Fremont, in the county of Dodge and State ofNebraska, have invented certain new and useful Improvements inDust-Consumers, of which the following is a specification.

My invention relates to new and useful improvements in granite or stonedust consumers. l

The objects of my invention are to provide a practical, economical andeiiicient dust consumer, for use in connection with granite or stoneneumatic surfacing machines, and which wi l obviate the inconvenienceand injurious eiects on the operator attending the use of thesesurfacers, caused by the dust filling the air, blinding the eyes,filling the nose and covering the clothes,- and settling on everythingin the room Where used. And further objects are to provide a dustconsumer that is easily applied to any of the ordinary ranite or stonepneumatic surfacers, wit lout altering the same, and using the exhaustfrom the surfacenmechanism in the operation of the device. I accomplishthese objects by the device illustrated in the accompanying drawings, inwhich,

Figure 1 is a side View showing the device in connection with the headof an ordi-A nary pneumatic granite or stone surfacing machine. Fig. 2is a sectional view of the device, with a dotted line showing thesurfacing point positioned ready for use. Fig. 3 is a View in detail ofthe reducing tubes and their relation to each other, as they ap pear onthe interior of the device.

Similar letters refer to similar parts Referring specifically to thedrawings, 1 is a circular funnel shaped hollow hood, with the upper orsmall end 2, provided with a tubular neck 3, in which is telescopicallyadjusted an extension pipe 4, adapted to close up around the lowerportion or steel' point of the surfacer, as hereafter described. Thishood 1 is provided in its side wall with an aperture 5, opening into adust c0nsuming hollow chamber, 6, which extends `horizontally andsubstantially at right angles thereto. This dust consuming chamber isclosed at all points except the aperture -at 5 and the bottom, where isprovided with an opening 7,- extending its entire len h, and throughwhich the refuse drops a cr transformation from dust into a congealed orsolid form.

8 is a tube vertically penetrating the uper wall of hood 1, and extendsdownwardly into the interior thereof. The upper end of this tube isadapted to a hose, 9, connecting it with the water supply tank, at 10,which is conveniently located on and attached to the lever of thesurfacer. The supplyl of water from tank 10 is regulated by an ordinaryvalve, at 11, inserted in hose 9.

12 is a tube extending horizontally throu h the side wall of hood 1, andforms a rig t angle or elbow 13, on the interior of the hood, with anarm 14 reaching to a point near tube 8, as it extends downwardly intothe interior of 'the hood 1, the tube 8 and the arm 14 falling centrallyin the opening 5 leading to the dust consuming chamber 6,

'and positioned in such manner as to cause the water passing throughtube 8 to fall directly on a plane with the end of arm 14, where it istransformed into spray in the operation of the mechanism, as hereinafterdescribed.

15 is an aperture in the hood 1, conveniently covered with screen toprevent stone chips from escaping, and is provided for the purpose ofobservation on the part of the operator in the conduct of his work.

Hangers, as at 16-16, are conveniently attached to the hood 1, and thedustlconsuming chamber 8, and ada ted to suspend the device by suitablehoo s to the framework of the surfacer when desired, though this is notnecessary to the successful operation of the device, as it can easily bemoved along with the hammer mechanism in passing over the stone.

An apron 17, is 'conveniently' attached to.'

.and adapted to o crate the hammer mechanism, and conveniently 'attachedby connect- ,ing hose tothe air reservoir used in the opf' eration'ofthe pneumatic hammer, 19 is the exhaust or discharge from the hammermechanism, and like 18 is rovided with the ordinary and usual cheervalves used 1n such connections.

20 is a pipe with elbows at cach end and adapted to adjustment on tube12 and the exhaust or discharge 19 in the operation of the machinery,thus providing a conduit for the exhaust, discharging the same into thehood 1 through tube 12 and arm 14.

21 is the ordinary hammer lever, and 22 the body of the hammermechanism, which is provided with a supporting framework, 23. The hammeris 'provided with a handle 24, and all of the ordinary attachments tothe pneumatic surfacer as commonly used.

Having described the construction of my device its operation is asfollows :-The steel point 4', ordinarily used in connection with graniteor stone pneumatic surfacing machines, is first inserted verticallydownward through the extension pipe 4, which is tele, scopicallyinserted in the tubular neck 2 of the small end 2 of the hood 1; theextension pipe 4 is then adjusted up over the point 4', extending to thebase of the hammer mechanism. The elbow arlns of pipe 20 are then placedover the exhaust 19 and the tube 12 leading into the hood 1 the hangers16-16 are then hooked to sta iles or eyes in the bottom of the hammerframework, and the `water tank 10 suitably secured to the lever 21, andthe tube 8 is connected therewith by hose 9. Being thus adjusted as toits parts, the air from the main reservoir is turned on at 18, the inletfor the air to the hammer mechanism, and this sets the hammer in motion.The air from the exhaust 19 of the hammer mechanism passes down the pipe20- and enters hood 1 through the tube 12. At the same time the water isforced through valve 11, permitting the same to lion' from tank 10through hose 9 and into tube 8, and upon passing therefrom into the hoodl, is suddenly and violently struck by the exhaust passing through tube12, striking it with such force as to convert it into spray, and forcingit through the aperture 5 and into the dust consuming chamber 6. At thesame time the exhaust passing out of tube 12, blows andl draws the dustmade in the operation of the steel point 4', into the dust consumingchamber 6, where it meets and mingles with the spray and is thusconverted into solid form, whereupon it drops out of vthe dust consumingchamber through the opening 7 therein, ready for removal.

The rapidity of the exhaust furnishes a constant supply of 'air in suchquantity as to continually lill the dust consuming cham ber with therising dust and spray when the machine is in operation, and in this waythe dust is rapidly and completely transformed into av solid mass, thusobviating the scattering of the same, covering the operators andinjuring their eyes, ears, nose and clothing.

Havin described my invention what I claim an desire to secure by LettersPatent tube extending horizontally through the side wall of the saidhood and provided with an elbow and arm on the interior thereof; and atube vertically penetrating the upper wall of the hood and extendingdownwardly therein, all substantially as set forth.

2. A dust consuming device of the character described, consisting of afunnel shaped hood, having a tubular neck and a pipe telescopicallyadjustable therein, and provided in its side wall with an openingleading to the dust consuming chamber; a dust consuming chamberconnected to said hood and extending substantially at right anglesthereto, and having an opening in the bottom extending longitudinallyits entire length; a tube extending horizontally through the side wallof the said hood and a pipe adapted thereto; a tube verticallypenetrating the upper wall of the hood and a hose and water tank adaptedto the said tube; hangers attached to the hood and an apron secured tothe large cir-cumfer-'nce thereof, all substantially as and for thepurposes set forth.

3. In a dust consuming device, the combination with a pneumaticsurfacing mechanism` provided with an air service pipe leading flom thereservoir to the hammerunechanism, of a funnel shaped hollow hood,having a tubular neck and a pipe telescopically adjustable therein andadapted to inclose the surfacing point of the mechanism;

a dust consuming cham er attached to thc hood having an aperturt` in thebottom; a

tube extending horizontally through the side wall of the hood andadapted to pipe connections with the exhaust of'- the hammer mechanism;a tube vertically penetrating the upper wall of the hood, adapted tohose connections with the water tank; a water tank connected with saidtube and supply and cut off attachments; hangers loosely attaching thehood and dust consuming chamber to the framework of the hammermechanism; and pipe and hose connections, all substantially as setforth.

In testimony whereof I aiiix my signature in presence of two witnesses.
